Erratum
The following PCI Compliance test failure is acceptable: Bit 15
(Bridge Configuration Retry Enable) in the Device Control
register (offset 8h) in the PCI Express Capability table must be
read-only and always return 0 as it is reserved for devices other
than PCI Express to PCI/PCI-X Bridges. Assertion 13A41D3E-
2576-41DC-A67C-525DA3637CEA This failure is acceptable
because this is a PCIe 1.1 feature and the WLP requires
compliance with only PCIe 1.0a.

Errata 1198
Preview Filter - Reserved "Impedance" bits in Pin Sense
response to digital pin widgetsThe original HD Audio 1.0
specification contains a notion of "presence detect", using
electrical impedance which was intended to apply only to analog
pins. However, the language of the specification was such that
it could be read to apply to digital pins as well - in particular, to
S/PDIF pins.
A DCN was released to extend the notion of presence detect to
digital pins - in particular, to HDMI pins. This repurposed one of
the impedance bits, which were thought to be unused in digital
pins, to mean "ELD valid."
The correct way for a S/PDIF pin to respond to a Pin Sense verb
is to set the highest bit (Presence Detect) to 1 or 0
corresponding to whether a S/PDIF connection is active; set the
ELD Valid bit to 0 (since there is no such thing as ELD for
S/PDIF); and set the rest of the bits, which are reserved for
digital pins, to 0.
This errata filter is a preview filter to allow hardware
manufacturers time to update any hardware that used the
impedance bits on digital pins.
